Patent GB-618617-A (GB)
Title: Blasting or boring apparatus
IPC: F42B1/02
Filed: 1946-11-04
Abstract: 618,617. Blasting devices. SOC. INDUSTRIELLE D'ENTREPRISE ET DE MECANIQUE. Nov. 4, 1946, No. 32739. Convention date, Nov. 7, 1945. [Class 9 (i)] Relates to a blasting device based on the " hollow" charge principle, and consists in providing an explosive charge 1 having a cavity 3 of substantially funnel-shaped crosssection and extending the length and width of the charge, the cavity being orientated in the direction of propagation of the detonation wave within the explosive and a priming charge 2 placed at one end of the charge 1. Furthermore, the cavity is such that a triangle BAC inscribed in the transverse section of the cavity having the outlet of the cavity as base BC has an apex angle A between 90 and 120 degrees. The cavity 3 may be lined with metal, thermo-setting plastic material or agglomerated material. This lining 4 may be extended to form walls 5, 6 giving the optimum set-back from the surface to be blasted when the charge 1 is placed in position. The profile of the cavity BAC may vary from the dihedral to the cylindrical form. Longitudinal grooves may be provided in the walls of the cavity. The lining 4 may be continued to form a water-tight compartment, Fig. 6, when the device is required for underwater use. The device can then be constructed by sliding one rigid tube within another and filling the space between the tubes with explosive, the inner tube serving as the cavity. Alternatively the outer tube may be a flexible sheath enclosing the explosive and inner tube. In this modification the explosive charges may have the end faces curved so that a number of charges can be assembled end-to-end within the flexible sheath. Specification 579,279 is referred to.

Title: Improvements in or relating to the densimetric separation of solid materials
IPC: B03B5/42
Filed: 1955-11-18
Abstract: 818,386. Washing granular materials. PREPARATION INDUSTRIELLE DES COMBUSTIBLES. Nov. 18, 1955 [Dec. 4, 1954], No. 33093/55. Class 82(2) In sink and float apparatus employing a magnetite suspension a washing drum 1 has a concentric rotatable enclosure 3 which, after spraying and draining of the products of the separation, receives the magnetite after its being magnetically separated from the diluted suspension obtained after the spraying, and lifts it to the upper part of the apparatus for return to the washing drum. Raw material is fed at B into the magnetite suspension L in the rotating drum 1 attached at Br to enclosure 3. The light fraction F flows over a weir on to the screen Cr which vibrates; the heavy fraction is carried round by paddles 2 and shoots b to be discharged at P on to an adjacent parallel section of screen Cr. Heavy medium drains through section A of the screen, passes to enclosure 4 and via bucket wheel Pa2 and demagnetizer D to shoot Cl and the bath L. The washings from the rest of screen Cr (M, N are rinsing sprays) pass to enclosure 5 where magnets Am attract the magnetite and carry it up to scrapers Ra which remove it from the magnets and whence it flows freely around the drum 1 via deflector Ba to the enclosure 4 and so to the bath L. The slurry water freed of magnetite is carried up by bucket wheel Pa3 and delivered to sprays M. Fresh water Q is added at sprays N whilst an amount Q overflows at D#. In Fig. 2 (not shown) is illustrated a form of apparatus having an external fixed magnet and demagnetizing device. Fig. 3 shows two separators in series which produce three fractions. P, F, and Fl. The separator II shows an arrangement slightly different from that of Fig. 1 (and I), in which the raw material fed at B gives a light product Fl and a heavy product which leaves by shoot C<SP>1</SP>l to enter the separator I. Corresponding parts of separator II with the exception of the shoots, are lettered and numbered as in Fig. 1 (and separator I).

Patent GB-1118373-A (GB)
Title: Preparation of modified vegetable phosphatides
IPC: C07F9/10
Filed: 1966-07-27
Abstract: A process for modifying hydrated vegetable phosphatides comprises contacting them with a dilute aqueous acid to provide a mixture of pH 2-5, maintaining the resulting emulsion at an elevated temperature suitably 50-100 DEG  C. until it breaks and separating off the phosphatide-containing phase.  Suitable hydrated phosphatides are those obtained from soyabean oil, groundnut oil, rapeseed oil and sunflower oil. The acid used is suitably an aliphatic carboxylic acid such as formic-, acetic-, lactic- or citric-acid and is conveniently added as a 10% by weight aqueous solution at room temperature.  The phosphatide containing phase can be dried by heating at less than 80 DEG  C. under reduced pressure. The acidified phosphatides so produced may be brought to a pH of 6-7 with the aid of weak organic bases such as an ethanolamine, e.g. monoethanolamine before drying. The hydrated phosphatides may be obtained by treating a phosphatide-containing crude oil extract from plant with 0.5-10% by weight of water.  The products are suitable as emulsifiers in oil-water systems such as animal feeding stuffs, cooking fats, mayonnaise and mayonnaise like products.  Groundnut oil emulsions may also be stabilized by the addition of the modified phosphatides (see Division C1).ALSO:A groundnutoil-water emulsion is prepared by adding a modified plant phosphatide to the oil-water mixture at 50 DEG C and shaking, the phosphatide being one prepared by treating a hydrated plant phosphatide with dilute acid (see Division C2).  Other specified emulsions are animal feeding stuffs, cooking fats, mayonnaise and mayonnaise like products.

Abstract: 1360332 Linear motors LA CELLOPHANE 24 July 1972 [5 Aug 1971] 34533/72 Heading H2A [Also in Division B5] An induction motor (Fig. 2) includes a magnetic circuit 1 of an inductor which carries a coil 2, the magnetic field of which produces induced currents in bars 3 embedded in a magnetic circuit, or yoke 4, of the secondary circuit, and this generates forces which are applied to the bars 3 and cause the secondary circuit to slide in the direction of the arrow. The bars made of conducting metal where the induced currents are formed may be detached from the magnetic circuit or yoke which serves to close the flux; the electrical circuit is thus detached from the magnetic circuit of the orginal rotor and the yoke of the latter is rendered an integral part of the inductor. It is also possible to substitute a conducting plate in the original assembly of bars of the electrical circuit of the secondary circuit. This assembly is shown in Fig. 3, in which the inductor consists of the magnetic circuit 1 and the coil 2 and also of the yoke 6. Further, it is possible to alter the yoke by hollowing out of it slots fitted with coils, and so produce motors with a double inductor as shown in Fig. 4, leading to more economical performance. Such linear motors may be formed with fixed inductors and sliding secondary circuits or vice versa. For the application of the motors to the stretching of plastics films see Division B5.
